In the \u003cstrong\u003e4.0L Cologne SOHC V6\u003c\/strong\u003e, continuous thermal cycling leads to ceramic core breakdown, chemical fouling, and excessive exhaust backpressure. This restriction chokes exhaust scavenge cycles, spikes combustion temperatures, degrades fuel economy, and inevitably triggers catalyst efficiency check engine lights.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct-replacement front assembly is constructed with heavy-gauge aluminized steel tubing to resist road corrosion and thermal stress. The high-efficiency ceramic monolith features an optimized precious-metal catalyst loading that restores OEM-grade emissions reduction for NOx, CO, and hydrocarbons. Precision-machined, thick-gauge connecting flanges mate directly to factory exhaust manifolds and intermediate pipes to prevent leaks under load. Pre-welded oxygen sensor bungs ensure accurate sensor placement in the exhaust stream, maintaining seamless closed-loop ECU fuel trimming without cutting or custom pipe adaptation.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2002-2004 Ford Explorer\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e4.0L Cologne SOHC V6 \/ U152\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e210 hp \/ 254 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e30447, 794165, 9112, 30454\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2002-2004 Ford Explorer 4.0L V6 (Production up to 03\/01\/2004)\u003c\/li\u003e\n  \u003cli\u003ePlacement: Front Undercar Assembly\u003c\/li\u003e\n  \u003cli\u003eExcludes Ford Explorer Sport 2-door models\u003c\/li\u003e\n  \u003cli\u003eExcludes 4.6L Modular V8 models\u003c\/li\u003e\n  \u003cli\u003eEPA Standard Tier-1 \/ LEV compliant (46-state legal; not legal for sale or use in CA, NY, CO, or ME)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the U152 Explorer?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2002-2004 Ford Explorer equipped with the \u003cstrong\u003e4.0L Cologne SOHC V6\u003c\/strong\u003e engine built up to March 1, 2004.\u003c\/p\u003e\n\n\u003ch4\u003eWill this resolve P0420 and P0430 efficiency codes?\u003c\/h4\u003e\n\u003cp\u003eYes, replacing depleted factory converters with this active catalyst assembly restores operational conversion thresholds and clears OBD-II catalyst efficiency codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Ford Durability Benchmark\u003c\/h3\u003e\n\u003cp\u003eBuilt to withstand the thermal and mechanical stresses of heavy hauling and off-pavement driving, this converter assembly maintains stable exhaust backpressure to protect low-end torque output throughout the vehicle service life.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67537900863736,"sku":"DS-E8ZW6TL7T","price":214.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-ford-explorer-2002-2004-4-0l-front-1.jpg?v=1790619551","url":"https:\/\/performancechiptuning.com\/products\/catalytic-converter-for-ford-explorer-2002-2004-4-0l-front","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
